User Facing Changes

If you are upgrading from v0.3.x to this version, please note that there are some configuration changes.

• Removed --l1.rpckind=bsc_fullnode
• Removed --l2.engine-sync
• Removed --l2.skip-sync-start-check
• To start engine-sync, use --syncmode=execution-layer (default value is consensus-layer)
• Added --l1.max-concurrency=20 to control the rate of requests to L1 endpoints.

After the Cancun/Ecotone hard fork, DA data will be submitted to the BSC network in blob format. Regular BSC nodes only retain blob data from the past 18 days. If you are syncing data from the genesis block or are more than 18 days behind the latest block, you will need to ensure that your configured L1 endpoint supports persisting blob data for a longer period of time. We will ensure that the snapshot provided by this snapshot repository is within the 18-day range, so you can also choose to use the snapshot to avoid relying on older blob data to start your new node.
